Four Essays on Applied Energy Economics and Policy
… the second chapter, we use data from the Texas ERCOT to study the impact of capacity payments in a stylized wholesale electricity market. We find that the introduction of capacity payments has two countervailing effects. On the one hand, it increases consumers’ bills. On the other hand, it …
